1996 Millenia Heater blowing cold air

[espc31]

I have a 1996 Millenia and the heater blows cold air no matter what setting it it is on. I replaced the thermostat and checked the coolant and it still blows cold. when the ac is on it blows cold as well. On the AC or heater it will only blow through the dashboard vents. Has anyone ever experienced this before?

I have a 2000 millenia and I had the same problem. I downloaded the repair manual for a 96 millenia, which is not exactly like the 2000 but here the site "http://rapidshare.com/files/51248650/Millenia-1996.rar". We took the radio out to see what we could find and at the same time my friend was reading over some things I had printed off. Come to find out it was the c/c computer needed to be reset. In order to do that you can find that on Pages U22-U26 of the manual. It was either that or it might have been where we took the negitive cable off the battery for about 2 minutes either way I have heat now without taking the dash out. If you can't download the manual let me know and I look at it again and explain it to you. Good Luck!

I have a 98 Millenia and every winter I have no heat. I have ac great all summer and when I switch it back to heat during the weather change the heat does not work. I have found that the door does not shut to allow the hot air to circulate into the cab due to lint obstructing the arm from moving. I found that the arm frees easily with a squirt of wd-40...has worked everytime for me and saved me the cost of taking it into the shop for a mechanic to repair.
